matlab 图像融合后 怎么求图像的均值,标准差啊?
diffX(1:M,N)=0; %%% the boundery set to 0 diffY(M,1:N)=0;diffX=diffX.*diffX;diffY=diffY.*diffY;AVEGRAD=sum(sum(diffX+diffY));AVEGRAD=sqrt(AVEGRAD\/2);AVEGRAD=AVEGRAD\/((M-1)*(N-1));end 我也在找呢,发现一个,共同参考下吧。参考资料:<a href="http:...

平均梯度的梯度公式
white210:平均梯度越大,图像层次越多,也就越清晰。其定义为:式中:F(i,j)为图像的第i行,第j列的灰度值;M、N分别为图像的总行数和总列数。单幅图像的平均梯度值计算MATLAB源程序:说明:该程序的作用是计算输入图像img的平均梯度值AVEGRAD平均梯度值可以衡量图像细节反差表达的能力,是图形融合...
武威市来曲回答: have difficulty doing sth 固定搭配
卜阎13326563315问: have difficulties to do 还是Have difficulty to do. - ?
武威市来曲回答: 楼上说的很对,have difficulty 后面要用动词的 ing 形式,而不能用不定式.这是讲英语的思维方式.但是,这就给那些喜欢用语法分析句子结构的人出了一个难题.difficulty 后面怎么能跟一个现在分词短语呢?这个动作并不是 difficulty 发出的啊...
卜阎13326563315问: have some difficulty 是用单数还是用复数 - ?
武威市来曲回答: difficulty可数与不可数都行.“have some difficulty” 表示“有某种困难”,“have some difficulties ”表示“有一些困难”,意思不同!difficulty n.困难,艰难,难事;有可数名词和不可数名词两种用法. ①用作不可数名词,意为"困难、艰难"...
卜阎13326563315问: have difficulties with和have difficulty with - ?
武威市来曲回答: have difficulty/trouble (in) doing sth. 在这里difficulty和trouble都不可数.some可以修饰不可数名词. 一般没有have difficulties doing sth. 这样的用法.
卜阎13326563315问: 做某事有麻烦,有问题为什么是:have problem doing;have difficulty doing - ?
武威市来曲回答: 下面这几种形式都有,只是有细微差异: 做某事有问题,有两种表达(单复数之分) have a problem (in) doing sth have problems (in) doing sth 做某事有困难: have difficulty (困难,抽象名词,不可数) (in)doing sth【更常用】 have difficulties(难事,抽象名词具体化,强调具体的艰难之事) (in)doing sth 做某事有麻烦 have trouble(不可数名词,单数) (in) doing sth 祝你开心如意!
卜阎13326563315问: have difficulties (in) doing 和have difficulties to do 有什么区别 - ?
武威市来曲回答: 动词不定式to do something表示某次的行为,而动名词doing something表示经常性的行为. 因此have difficulty to do something表示某一次做某事有困难;而have difficulty (in) doing something表示某事要做一直有困难.
卜阎13326563315问: have difficulty with有这种结构吗 - ?
武威市来曲回答: 1. have difficulty with sth 在某事上有问题 2. have difficulty (in) doing sth 做某事有困难3. have difficulties with sth 在某事上碰到麻烦 望采纳!
卜阎13326563315问: have difficulties doing sth是什么意思? - ?
武威市来曲回答: Have difficulties doing something.做某事有困难.如He has difficulties speaking English.
卜阎13326563315问: have difficulty with sth中difficulty要不要遍复数??
武威市来曲回答: difficulty 可以是可数(表示具体)也可以不可数名词(表示抽象). 有以下两个典型词组 have difficulty in doing / with sth. 表示抽象,用不可数 come across difficulties/ overcome difficulties 表示具体困难,用可数.
卜阎13326563315问: have difficuly(ies) in 咋...咋...回事呀! - ?
武威市来曲回答: have difficulties in 是表示在某某方面做起事来有困难,当然,这种困难一般用复数形式difficulties,表示泛指,即不明确指定困难到底是什么. have a difficulty in 是一种明确的说法,后面要紧接着说明what is the difficulty.如 I have difficulties in learning English.我学英语有些困难.I have a difficulty in learning English. That is I can not spell the word correctly. 我学英语有个困难,就是我总是拼写不对单词.
